Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492602, here are decompositions:

5 + 31492597 = 31492602
61 + 31492541 = 31492602
73 + 31492529 = 31492602
109 + 31492493 = 31492602
131 + 31492471 = 31492602
149 + 31492453 = 31492602
173 + 31492429 = 31492602
179 + 31492423 = 31492602

Showing the first eight; more decompositions exist.
